534c97b095 Merge branch 'timers-nohz-for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/tip/tip 
Pull 'full dynticks' support from Ingo Molnar:
 "This tree from Frederic Weisbecker adds a new, (exciting! :-) core
  kernel feature to the timer and scheduler subsystems: 'full dynticks',
  or CONFIG_NO_HZ_FULL=y.

  This feature extends the nohz variable-size timer tick feature from
  idle to busy CPUs (running at most one task) as well, potentially
  reducing the number of timer interrupts significantly.

  This feature got motivated by real-time folks and the -rt tree, but
  the general utility and motivation of full-dynticks runs wider than
  that:

   - HPC workloads get faster: CPUs running a single task should be able
     to utilize a maximum amount of CPU power.  A periodic timer tick at
     HZ=1000 can cause a constant overhead of up to 1.0%.  This feature
     removes that overhead - and speeds up the system by 0.5%-1.0% on
     typical distro configs even on modern systems.

   - Real-time workload latency reduction: CPUs running critical tasks
     should experience as little jitter as possible.  The last remaining
     source of kernel-related jitter was the periodic timer tick.

   - A single task executing on a CPU is a pretty common situation,
     especially with an increasing number of cores/CPUs, so this feature
     helps desktop and mobile workloads as well.

  The cost of the feature is mainly related to increased timer
  reprogramming overhead when a CPU switches its tick period, and thus
  slightly longer to-idle and from-idle latency.

  Configuration-wise a third mode of operation is added to the existing
  two NOHZ kconfig modes:

   - CONFIG_HZ_PERIODIC: [formerly !CONFIG_NO_HZ], now explicitly named
     as a config option.  This is the traditional Linux periodic tick
     design: there's a HZ tick going on all the time, regardless of
     whether a CPU is idle or not.

   - CONFIG_NO_HZ_IDLE: [formerly CONFIG_NO_HZ=y], this turns off the
     periodic tick when a CPU enters idle mode.

   - CONFIG_NO_HZ_FULL: this new mode, in addition to turning off the
     tick when a CPU is idle, also slows the tick down to 1 Hz (one
     timer interrupt per second) when only a single task is running on a
     CPU.

  The .config behavior is compatible: existing !CONFIG_NO_HZ and
  CONFIG_NO_HZ=y settings get translated to the new values, without the
  user having to configure anything.  CONFIG_NO_HZ_FULL is turned off by
  default.

  This feature is based on a lot of infrastructure work that has been
  steadily going upstream in the last 2-3 cycles: related RCU support
  and non-periodic cputime support in particular is upstream already.

  This tree adds the final pieces and activates the feature.  The pull
  request is marked RFC because:

   - it's marked 64-bit only at the moment - the 32-bit support patch is
     small but did not get ready in time.

   - it has a number of fresh commits that came in after the merge
     window.  The overwhelming majority of commits are from before the
     merge window, but still some aspects of the tree are fresh and so I
     marked it RFC.

   - it's a pretty wide-reaching feature with lots of effects - and
     while the components have been in testing for some time, the full
     combination is still not very widely used.  That it's default-off
     should reduce its regression abilities and obviously there are no
     known regressions with CONFIG_NO_HZ_FULL=y enabled either.

   - the feature is not completely idempotent: there is no 100%
     equivalent replacement for a periodic scheduler/timer tick.  In
     particular there's ongoing work to map out and reduce its effects
     on scheduler load-balancing and statistics.  This should not impact
     correctness though, there are no known regressions related to this
     feature at this point.

   - it's a pretty ambitious feature that with time will likely be
     enabled by most Linux distros, and we'd like you to make input on
     its design/implementation, if you dislike some aspect we missed.
     Without flaming us to crisp! :-)

  Future plans:

   - there's ongoing work to reduce 1Hz to 0Hz, to essentially shut off
     the periodic tick altogether when there's a single busy task on a
     CPU.  We'd first like 1 Hz to be exposed more widely before we go
     for the 0 Hz target though.

   - once we reach 0 Hz we can remove the periodic tick assumption from
     nr_running>=2 as well, by essentially interrupting busy tasks only
     as frequently as the sched_latency constraints require us to do -
     once every 4-40 msecs, depending on nr_running.

  I am personally leaning towards biting the bullet and doing this in
  v3.10, like the -rt tree this effort has been going on for too long -
  but the final word is up to you as usual.

  More technical details can be found in Documentation/timers/NO_HZ.txt"

150a8dcf10 ARM: arm-soc board specific changes for 3.10, part 1 
These changes are all for board specific files. These used to make up a
 large portion of the ARM changes in the past, but as we are generalizing
 the support and moving to device tree probing, this has gotten
 significantly smaller. The only platform actually adding new code here
 at the moment is Renesas shmobile, as they are still busy converting
 their code to device tree and have not come far enough to not need it.

6fa52ed33b ARM: arm-soc driver changes for 3.10 
This is a rather large set of patches for device drivers that for one
 reason or another the subsystem maintainer preferred to get merged
 through the arm-soc tree. There are both new drivers as well as
 existing drivers that are getting converted from platform-specific
 code into standalone drivers using the appropriate subsystem
 specific interfaces.
 
 In particular, we can now have pinctrl, clk, clksource and irqchip
 drivers in one file per driver, without the need to call into
 platform specific interface, or to get called from platform specific
 code, as long as all information about the hardware is provided
 through a device tree.
 
 Most of the drivers we touch this time are for clocksource. Since
 now most of them are part of drivers/clocksource, I expect that we
 won't have to touch these again from arm-soc and can let the
 clocksource maintainers take care of these in the future.
 
 Another larger part of this series is specific to the exynos platform,
 which is seeing some significant effort in upstreaming and
 modernization of its device drivers this time around, which
 unfortunately is also the cause for the churn and a lot of the
 merge conflicts.
 
 There is one new subsystem that gets merged as part of this series:
 the reset controller interface, which is a very simple interface
 for taking devices on the SoC out of reset or back into reset.
 Patches to use this interface on i.MX follow later in this merge
 window, and we are going to have other platforms (at least tegra
 and sirf) get converted in 3.11. This will let us get rid of
 platform specific callbacks in a number of platform independent
 device drivers.

  existing drivers that are getting converted from platform-specific
  code into standalone drivers using the appropriate subsystem specific
  interfaces.

  In particular, we can now have pinctrl, clk, clksource and irqchip
  drivers in one file per driver, without the need to call into platform
  specific interface, or to get called from platform specific code, as
  long as all information about the hardware is provided through a
  device tree.

  Most of the drivers we touch this time are for clocksource.  Since now
  most of them are part of drivers/clocksource, I expect that we won't
  have to touch these again from arm-soc and can let the clocksource
  maintainers take care of these in the future.

  Another larger part of this series is specific to the exynos platform,
  which is seeing some significant effort in upstreaming and
  modernization of its device drivers this time around, which
  unfortunately is also the cause for the churn and a lot of the merge
  conflicts.

  There is one new subsystem that gets merged as part of this series:
  the reset controller interface, which is a very simple interface for
  taking devices on the SoC out of reset or back into reset.  Patches to
  use this interface on i.MX follow later in this merge window, and we
  are going to have other platforms (at least tegra and sirf) get
  converted in 3.11.  This will let us get rid of platform specific
  callbacks in a number of platform independent device drivers."

3fbc81e3c0 hwmon: (lm75) Add support for the Dallas/Maxim DS7505

0cd2c72d76 hwmon: (lm75) Tune resolution and sample time per chip 
Most LM75-compatible chips can either sample much faster or with a
much better resolution than the original LM75 chip. So far the lm75
driver did not let the user take benefit of these improvements. Do it
now.

I decided to almost always configure the chip to use the best
resolution possible, which also means the longest sample time. The
only chips for which I didn't are the DS75, DS1775 and STDS75, because
they are really too slow in 12-bit mode (1.2 to 1.5 second worst case)
so I went for 11-bit mode as a more reasonable tradeoff. This choice is
dictated by the fact that the hwmon subsystem is meant for system
monitoring, it has never been supposed to be ultra-fast, and as a
matter of fact we do cache the sampled values in almost all drivers.

If anyone isn't pleased with these default settings, they can always
introduce a platform data structure or DT support for the lm75. That
being said, it seems nobody ever complained that the driver wouldn't
refresh the value faster than every 1.5 second, and the change made
it faster for all chips even in 12-bit mode, so I don't expect any
complaint.

Pull nfsd changes from J Bruce Fields:
 "Highlights include:

   - Some more DRC cleanup and performance work from Jeff Layton

   - A gss-proxy upcall from Simo Sorce: currently krb5 mounts to the
     server using credentials from Active Directory often fail due to
     limitations of the svcgssd upcall interface.  This replacement
     lifts those limitations.  The existing upcall is still supported
     for backwards compatibility.

   - More NFSv4.1 support: at this point, if a user with a current
     client who upgrades from 4.0 to 4.1 should see no regressions.  In
     theory we do everything a 4.1 server is required to do.  Patches
     for a couple minor exceptions are ready for 3.11, and with those
     and some more testing I'd like to turn 4.1 on by default in 3.11."

Fix up semantic conflict as per Stephen Rothwell and linux-next:

Commit 030d794bf4 ("SUNRPC: Use gssproxy upcall for server RPCGSS
authentication") adds two new users of "PDE(inode)->data", but we're
supposed to use "PDE_DATA(inode)" instead since commit d9dda78bad
("procfs: new helper - PDE_DATA(inode)").

The old PDE() macro is no longer available since commit c30480b92c
("proc: Make the PROC_I() and PDE() macros internal to procfs")

Pull i2c changes from Wolfram Sang:

 - an arbitration driver.  While the driver is quite simple, it caused
   discussion if we need additional arbitration on top of the one
   specified in the I2C standard.  Conclusion is that I accept a few
   generic mechanisms, but not very specific ones.

 - the core lost the detach_adapter() call.  It has no users anymore and
   was in the way for other cleanups.  attach_adapter() is sadly still
   there since there are users waiting to be converted.

 - the core gained a bus recovery infrastructure.  I2C defines a way to
   recover if the data line is stalled.  This mechanism is now in the
   core and drivers can now pass some data to make use of it.

 - bigger driver cleanups for designware, s3c2410

 - removing superfluous refcounting from drivers

 - removing Ben Dooks as second maintainer due to inactivity.  Thanks
   for all your work so far, Ben!

 - bugfixes, feature additions, devicetree fixups, simplifications...

5975a2e095 KVM: PPC: Book3S: Add API for in-kernel XICS emulation 
This adds the API for userspace to instantiate an XICS device in a VM
and connect VCPUs to it.  The API consists of a new device type for
the KVM_CREATE_DEVICE ioctl, a new capability KVM_CAP_IRQ_XICS, which
functions similarly to KVM_CAP_IRQ_MPIC, and the KVM_IRQ_LINE ioctl,
which is used to assert and deassert interrupt inputs of the XICS.

The XICS device has one attribute group, KVM_DEV_XICS_GRP_SOURCES.
Each attribute within this group corresponds to the state of one
interrupt source.  The attribute number is the same as the interrupt
source number.

This does not support irq routing or irqfd yet.

78df969550 dma-buf: replace dma_buf_export() with dma_buf_export_named() 
For debugging purposes, it is useful to have a name-string added
while exporting buffers. Hence, dma_buf_export() is replaced with
dma_buf_export_named(), which additionally takes 'exp_name' as a
parameter.

For backward compatibility, and for lazy exporters who don't wish to
name themselves, a #define dma_buf_export() is also made available,
which adds a __FILE__ instead of 'exp_name'.

e2a8b0a779 Documentation/sysrq: fix inconstistent help message of sysrq key 
Currently help message of /proc/sysrq-trigger highlight its
upper-case characters, like below:

      SysRq : HELP : loglevel(0-9) reBoot Crash terminate-all-tasks(E)
      memory-full-oom-kill(F) kill-all-tasks(I) ...

this would confuse user trigger sysrq by upper-case character, which is
inconsistent with the real lower-case character registed key.

This inconsistent help message will also lead more confused when
26 upper-case letters put into use in future.

This patch fix sysrq documentation.

151173e8ce Highlights: 
- OpenFirmware/DeviceTree support for the Power Supply core: the core now
   automatically populates supplied_from hierarchy from the device tree.
   With these patches chargers and batteries can now lookup each other
   without the board files support shim. Rhyland Klein at NVIDIA did the
   work;
 
 - New ST-Ericsson ABX500 hwmon driver. The driver is heavily using the
   AB85xx core and depends on some recent changes to it, so that is why the
   driver comes through the battery tree. It has an appropriate ack from
   the hwmon maintainer (i.e. Guenter Roeck). Martin Persson at ST-Ericsson
   and Hongbo Zhang at Linaro authored the driver;
 
 - Final bits to sync AB85xx ST-Ericsson changes into mainline. The changes
   touch mfd parts, but these were acked by the appropriate MFD maintainer
   (i.e. Samuel Ortiz). Lee Jones at Linaro did most of the work and lead
   the submission process.
 
 Minor changes, but still worth mentioning:
 
 - Battery temperature reporting fix for Nokia N900 phones;
 - Versatile Express poweroff driver moved into drivers/power/reset/.
 - Tree-wise: use devm_kzalloc() where appropriate;
 - Tree-wise: dev_pm_ops cleanups/fixes.

3094566959 Merge branch 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/jikos/trivial 
Pull fixup for trivial branch from Jiri Kosina:
 "Unfortunately I made a mistake when merging into for-linus branch, and
  omitted one pre-requisity patch for a few other patches (which have
  been Acked by the appropriate maintainers) in the series.  Mea culpa
  maxima, sorry for that."

The trivial branch added %pSR usage before actually teaching vsnprintf()
about the 'R' part of %pSR.  The 'R' causes the symbol translation to do
a "__builtin_extract_return_addr()" before symbol lookup.

That said, on most architectures __builtin_extract_return_addr() isn't
likely to do anything special, so it probably is not normally
noticeable.

  vsprintf: Add extension %pSR - print_symbol replacement
 2013-04-30 13:47:37 -07:00
Joe Perches
b0d33c2bd7 vsprintf: Add extension %pSR - print_symbol replacement 
print_symbol takes a long and converts it to a function
name and offset.  %pS does something similar, but doesn't
translate the address via __builtin_extract_return_addr.
%pSR does the translation.

This will enable replacing multiple calls like
	printk(...);
	printk_symbol(addr);
	printk("\n");
with a single non-interleavable in dmesg
	printk("... %pSR\n", (void *)addr);

Update documentation too.

Linus Torvalds
191a712090 Merge branch 'for-3.10' of git://git.kernel.org/pub/scm/linux/kernel/git/tj/cgroup 
Pull cgroup updates from Tejun Heo:

 - Fixes and a lot of cleanups.  Locking cleanup is finally complete.
   cgroup_mutex is no longer exposed to individual controlelrs which
   used to cause nasty deadlock issues.  Li fixed and cleaned up quite a
   bit including long standing ones like racy cgroup_path().

 - device cgroup now supports proper hierarchy thanks to Aristeu.

 - perf_event cgroup now supports proper hierarchy.

 - A new mount option "__DEVEL__sane_behavior" is added.  As indicated
   by the name, this option is to be used for development only at this
   point and generates a warning message when used.  Unfortunately,
   cgroup interface currently has too many brekages and inconsistencies
   to implement a consistent and unified hierarchy on top.  The new flag
   is used to collect the behavior changes which are necessary to
   implement consistent unified hierarchy.  It's likely that this flag
   won't be used verbatim when it becomes ready but will be enabled
   implicitly along with unified hierarchy.

   The option currently disables some of broken behaviors in cgroup core
   and also .use_hierarchy switch in memcg (will be routed through -mm),
   which can be used to make very unusual hierarchy where nesting is
   partially honored.  It will also be used to implement hierarchy
   support for blk-throttle which would be impossible otherwise without
   introducing a full separate set of control knobs.

   This is essentially versioning of interface which isn't very nice but
   at this point I can't see any other options which would allow keeping
   the interface the same while moving towards hierarchy behavior which
   is at least somewhat sane.  The planned unified hierarchy is likely
   to require some level of adaptation from userland anyway, so I think
   it'd be best to take the chance and update the interface such that
   it's supportable in the long term.

   Maintaining the existing interface does complicate cgroup core but
   shouldn't put too much strain on individual controllers and I think
   it'd be manageable for the foreseeable future.  Maybe we'll be able
   to drop it in a decade.

Fix up conflicts (including a semantic one adding a new #include to ppc
that was uncovered by header the file changes) as per Tejun.
